Use of perching method sees a gradual rise among farmers of the district as they are opting for environment-friendly ways to check harmful pests as well as reduce the use of pesticides.
In the perching method, farmers set bamboo poles and branches of trees on crop fields at regular intervals so that pest-eating birds can sit there.
Magpie, martin, owl, sparrow and parakeet sit on the branches and eat different types of pest. As a result the harmful pests are decreasing and the birds are increasing day by day.
About 60 percent of paddy fields in the district has been brought under this perching method, said Aftab Uddin, deputy director of Department of Agricultural Extension, Bagerhat.
During a recent visit to different villages in Kachua upazila, this correspondent found the birds sitting on the branches at the paddy fields to eat pests.
Meanwhile, the farmers are resisting the hunters to kill the bug-eating birds as it helps them increase the agricultural production and decrease the use of pesticides.
Farmer Abed Sheikh of Badal village in the upazila said he has been getting good result since he set 40 branches on his three bighas of crop land after planting seeds over a month ago.
Besides helping to produce chemical-free healthy food crops, the perching method is reducing his production cost as he does not need to spend money for using chemical pesticides, said Abed.
It is a matter of joy that the number of birds is increasing day by day due to the environment-friendly way to check harmful pests, he said.
Another farmer Sanata Das said he is also using the same environment-friendly method on his crop land to check the pests. The process is cheap and easy.
